FOLDING FRAME FOR MOSQUITO-BARS.

jaraoso.

To all whom it may concern:

Be it known that I, EVA TYNER, a citizen of the United States, residingat Canon City, in the county of Fremont and State of Colorado, haveinvented certain new and useful Improvements in Folding Frames forMosquito-Bars, of which the following is a specification, referencebeing had to the accompanying drawings.

My invention relates to improvements in frames or supports for mosquitobars or net canopies, and its object is to provide a simple andpractical device of this character which may be compactly folded whennot in use, and which may be readily set up and used on a babys crib, abed, a table or other object for supporting a netting or canopy whichwill exclude flies, mosquitos and other insects.

With the above and other objects in view, the invention consists of thenovel construction, combination and arrangement of parts, hereinafterfully described and claimed, and illustrated in the accompanyingdrawings in which:

Figure 1 is a perspective view of my improved folding frame in its openposition; Fig. 2 is a transverse sectional view, the mosquito bar orcanopy being indicated in dotted lines; Fig. 3 is a detail section takenon the plane indicated by the line 44 in Fig. 2; Fig. 4 is a detailperspective view of the sliding catch; and Fig. 5 is a plan view of theframe folded.

My improved folding frame or support for net canopies or mosquito barscomprises two similar side members 1 united by inwardly folding endmembers 2. The side members 1 are each formed from a single piece ofheavy wire or metal rod by bending it at suitable points to providestraight central portions 3 and downwardly and outwardly inclinedportions 4, which latter form supporting legs.

The end members 2 are each formed of two hingedly connected halfsections 5, 6, which are hingedly connected to opposing legs 4 andadapted to fold inwardly to bring the two side members 1 close togetherso that the frame when folded will occupy but little space. The halfsections 5, 6, are each formed from a single piece of heavy wire bentinto U-form and having their closed or connecting portions? formingpivots and united by a sheet metal hinge loop 8. The

extremities of the parallel arms of the U- shaped sections 5, 6, arebent to form hinge eyes 9 which latter engage and rotate on the legs 4,as shown more clearly in Figs.

2 and 3.

In order to prevent the end members 2 from collapsing when the frame isset for use I provide on each of said members a sliding catch orfastener 11 which is constructed from a suitable piece of sheet metaland has a tubular end 12 to slide on one of the arms of one of the halfsections of said member, and the other end of said fastener 11 beingchannel or U-shaped, as shown at 13, and-adapted to slide over andengage the correspondmg arm of the opposing sect1on of the end memberwhen such member is in open position, as will be understood.

on reference to Figs. 1 and 2.

In order to prevent a mosquito bar or net' canopy, which is indicated atA in Fig. 2,

from sagging in the center of the frame, cords, wires, chains or similarflexible elements 14 are arranged diagonally between-1 Thesethe cornersof the side members 1. elements 14 are attached to eyes or hooks formedpreferably from pieces of wire 15v which are bent around and secured tothe up-- per portions of the legs 4 immediately be-- neat-h the upperhinge eyes 9, whereby these wire hooks serve not only as attaching meanafor the cords or elements 14, but also as stops.-

for preventing the end members from Slip) ping downwardly on the legs 4.The cords or elements 14 will, of course, drop within the frame when thelatter is folded or collapsed.

From the foregoing it will be seen that my invention provides anexceedingly simple and inexpensive frame which will effeotively supporta mosquito bar over a bed or crib, or a net canopy over a table or anyother object. The peculiar construction of the device not only enablesit to be produced at a small cost but permits it to be quickly andeasily set up for use or folded for stor age or trans ortation. Vhen setup for use and fastene it will be exceedingly rigid and effectivelysupport the mosquito bar or canopy.

While the present embodiment of the instood that the device may be usedfor supporting a net canopy over a, dining table and for various otherpurposes.

. Having thus described the inventiongvhat is claimed is:

1. A device of the character described comprising two side members eachformed from a piece of Wire by bending it at suitable points to providea central portion and depending. legs, inwardly folding end memberscomposed o f half sections, each of the latter being formed from a pieceof wire bent into Uvfor m. and having the extremities of its arms bentto form hinge eyes Whichengage the legs, a hinge strap uniting theclosed portions of the two U-shaped half sections, a sliding catch foreach end member mounted for. sliding movementon onehalf section of thesame and having a channel portion to engage the, opposing half section,and flexible elements between the two side members.

2. A. device of the character described comprisingtwo side-members eachhaving side bars and downwardly extending legs, inwardly folding endmembers each composed of hingedly. connected half sections, the latterhaving at their outer ends eyes to loosely engage the, legs, wherebysaid sections are hingedly connected to the legs, flexible elements tosupport a mosquito bar or canopy at the central portion of the frame,and attaching means for said elements arranged on said legs beneath theeyes on the sections of the end members, whereby said fastening meansfor the elements will prevent the endmembers from slipping ownwardly onthe legs.

3. A device of the character described comprising two side members eachformed from a piece of Wire by bending it at suitable points to providea central portion and depending legs, inwardly folding end memi mi e...
